不同整地措施对朝阳地区山地黑果腺肋花楸栽植效果的影响

针对辽宁朝阳地区水土流失治理和经济林发展现状,将黑果腺肋花楸这一优良生态经济型树种应用于山地造林实践中,研究了不同措施对朝阳山地黑果腺肋花楸栽植效果的影响.结果 表明:4种整地方式(反坡梯田、水平阶、鱼鳞坑、水平梯田)与对照相比,显著提高了造林成活率和保存率,以修筑水平梯田法为最佳的整地方式,黑果腺肋花楸的平均成活率和...

Effects of Different Site Preparation Measures on the Planting Effect of Aronia prunifolia in Mountainous Areas in Chaoyang Area

Aiming at the current situation of soil erosion control and economic forest development in Chaoyang area in Liaoning Province,the excellent eco-economic tree species of Aronia prunifolia was applied to the practice of mountain afforestation,and the effect of different measures on the planting effect of Aronia prunifolia in the Chaoyang mountain area was studied.Result shows that the four land preparation methods(reverse slope terraces,horizontal terraces,fish scale pits&horizontal terraces)significantly improve the survival rate and preservation rate of afforestation compared with the control.The construction of horizontal terraces is the optimal land preparation method.The average survival rate&preservation rate of Aronia prunifolia is 96.0%and 94.3%,respectively.Use horizontal terraced field preparation,and apply different dosages of water-retaining agent(0,0.5,1.5,2.5&3.5 g·tree^-1)into the backfill soil to control the survival rate of seedlings in the very year,seedling height,and ground diameter growth in the very year.All have different degrees of influence,with the application of 2.5 g·tree^-1water-retaining agent with the highest survival rate;application of 3.5 g·tree^-1water-retaining agent has the largest average tree height and average ground diameter,but it is not significantly different from the 2.5 g·tree^-1treatment Considering the cost of water-retaining agent,it is recommended to use 2.5 g·tree^-1in production.
